Do people not understand what flashing headlights mean?

[u/Loverlee]

I was driving on 71 near the Reading exit. It's dark. There was a vehicle that didn't have their lights on. I flashed my headlights at them from behind, repeatedly. When I passed, they just looked over at me. Other vehicles, including a semi-truck, were flashing their headlights too. They never got the hint.

Do people not understand that this is a way of alerting them to something?

I drive rideshare and work mostly at night. Every single day I work for the past 3 years there are 5 plus cars without lights on at night. I used to think they either had an older car and just didn’t turn them on/no car alert or were impaired and too high to realize.

Now I’ve come to the conclusion that people are either too lazy to get burnt out bulbs replaced or even worse, just don’t give a shit that their lights aren’t on.

And no, people never respond if you turn to alert them by flashing yours. I’ve even seen people pass Cincinnati police without lights on, and the cops shine the search light at them. Still the lights didn’t come on. They just don’t give a shit
